null in args leads to an invalid argType

[Hypnosphi]

export default {
  title: 'Title,

  args: {foo: null}
};

leads to following error in preview:

Cannot read property 'defaultValue' of undefined

This is especially painful in connection with #12729

It only reproduces if you don't use docs addon

This is the same underlying issue as #12540, although I haven’t tried what would happen to this in the Storybook UI.
